No it is Subaru's variable valve timing. AVCS = active valve control system IIRC.

Subaru AVCS is a lot like Honda VTec. Its not an extra aftermarket device(Like the Apexi AVC-R), its a feature of the engine.

except when "VTEC kicks in", it causes the car to gain torque on the higher rpms...

AVCS aids for the lower-rpm stuff.

put another way, if you disable the AVCS system on your STI, you will lose low-end torque but high-rpm power will remain the same.

It's kind of like VTEC in reverse.
